FFmpeg Cheat Sheet
==================

## Re-encode a movie

Re-encode video while preserving audio, subtitles, chapters, etc.

### Regular movie

```sh
ffmpeg -i input.mkv -map 0 -c:a copy -c:s copy -c:v libx264 -preset slow -tune film output.mkv
```

### Animation movie

```sh
ffmpeg -i input.mkv -map 0 -c:a copy -c:s copy -c:v libx264 -preset slow -tune animation output.mkv
```

### Others `-tune` options

- `grain`: preserves the grain structure in old, grainy film material
- `stillimage`: good for slideshow-like content
- `fastdecode`: allows faster decoding by disabling certain filters
- `zerolatency`: good for fast encoding and low-latency streaming

Read [Encode/H.264](https://trac.ffmpeg.org/wiki/Encode/H.264) for more details.

## Copy all tracks

```sh
ffmpeg -i input.mkv -map 0 -c copy output.mkv
```

### Without audio

```sh
ffmpeg -i input.mkv -map 0 -c copy -an output-no-audio.mkv
```

### Without video

```sh
ffmpeg -i input.mkv -map 0 -c copy -vn output-no-video.mkv
```
